Boon Companions

Black-bellied whistling ducks (Dendrocygna autumnalis) ~ Lafitte’s Cove Nature Preserve

According to various dictionaries, both the word ‘boon’ and the phrase ‘boon companion’ are tending toward obsolescence.  Nevertheless, ‘boon companion’ is exactly the phrase that came to mind when I encountered this assortment of avian pairs on Sunday afernoon. They certainly seemed to fit the definition of ‘boon companion’ from the 1560s:  “a convivial friend or close intimate, someone with whom one enjoys spending time or sharing activities.”

Foraging white-faced ibis (Plegadis chihi) & snowy egret (Egretta thula) ~ Brazoria Wildlife Refuge

While it makes sense that members of the same species would enjoy hanging out together, cross-species companionship isn’t unknown. Many waterbirds engage in what’s known as commensal feeding, practices that benefit both members of the pair:

In commensal associations, members of one species assist the foraging of another, but incur no significant costs and receive no benefits. One of the more common commensal associations involves “beaters,” which stir up prey, and “attendants,” which simply follow in their footsteps taking whatever comes their way.
Many waterbirds, marsh birds, and shorebirds attend particular beater species. Great and Snowy Egrets attend cormorants; Snowy Egrets, Tricolored Herons, and Great Egrets attend mergansers. Some attendants will follow more than one beater species. Enterprising American Coots attend Canvasbacks, Tundra Swans, Mallards, pintails, and Redheads. In water of swimming depth, Wilson’s Phalaropes will follow Northern Shovelers; where they can wade, they will often forage behind American Avocets.

Simple proximity doesn’t always guarantee that a pair of birds are feeding commensally, but after watching this ibis and egret for a half-hour, I became certain they were sharing a meal.

Napping double-crested cormorants (Phalacrocorax auritus)
On the other hand, most of the cormorants seemed ready for after-dinner naps. When I stopped to admire this pair, they deigned to look at me once before re-tucking their heads into their feathery pillows: perhaps to dream of fish in the afternoon warmth.

Bringing Broadway Home

Yes, the Corona virus is serious. Its spread is worrying, just as the willingness of people across the country to stay at their posts in retail shops, hospitals, doctors’ offices, and grocery stores is more than admirable.

Still, there are frustrations and tensions as the world attempts to navigate its way through essentially uncharted waters. There’s anger at politicians and hoarders, befuddlement in the face of empty shelves, and a strong desire for easy or quick answers which refuse to come.

Given the realities, a little humor can be a relief, and when a friend passed on this video (thanks, Jeanie!), I laughed all the way through one of the best bits of parody I’ve seen. No, it’s not entirely safe for work, but since most people either aren’t working or are working from home, that’s not much of an issue. Enjoy!

When the World Goes to the Birds

Lafitte’s Cove ~ Galveston Island

With tourists being encouraged to leave the Island, weekenders staying in town, and full-time residents of Galveston’s west end more-or-less sequestered in their homes, much of the Island’s bird population continues to wander at will. 

Here, a pair of white ibis (Eudocimus albus) forage in a traffic median at the entrance to the Lafitte’s Cove subdivision. My hunch is that the new mulch around the plantings is filled with good things to eat, and this pair decided to visit the buffet. Notice that while the bird on the left is wide-eyed, the one on the right has closed it’s ‘third eyelid,’ a nictitating membrane (from Latin nictare, to blink), that helps to protect the eyes of birds, as well as various reptiles, mammals, and fishes. Wise bird, with all those thorns around.
